Answer: D. y = -4x + 4
Step-by-step explanation:
Notice that the y-intercept is when x is zero and the x intercept is when y is 0.
and to write in the equation in slope intercept form , you will need the slope and the intercept.
We will use the y and x intercepts to find the slope, by find the difference in their y coordinates and dividing it by the difference in their x coordinates.
y intercept: ( 0,4)
x intercept: (1,0)
y coordinates difference: 4 - 0 = 4
x coordinates difference: 0 - 1 = - 1
Slope: 4/-1 = -4
Since the slope is -4 and the the y intercept is 4 , the equation will be
y = -4x + 4
Answer: Taxi driver has at most $10 to spend on the cab ride, he can travel at most 12.7 miles.
Step-by-step explanation:
A Taxi driver charges a flat rate = 7.25 dollars
taxi fare for 1 mile = 0.65 dollars
Suppose we consider Total money taxi driver can spend = 10 dollars
Let taxi driver travel x miles
Total charges = flat rate charge + taxi fare for each mile(distance) travelled
Find the value y = [?] + [?]x
suppose these two question marks indicate z1,z2
replace with y=10 and z1=1.75 and z2=0.65 values
Then y = [z1] + [z2]x
10 = 1.75 + 0.65(x)
0.65(x) = 10 - 1.75
0.65(x)= 8.25
x = 8.25/0.65
x = 12.7 miles
If Taxi driver has at most $10 to spend on the cab ride, he can travel at most 12.7 miles.

Answer:
7/4
Step-by-step explanation:
Answer:
25, 50, and 105.
Step-by-step explanation:
Let the first angle be A, the second angle be B, and the third angle be C.
First, the sum of the three angles in a triangle is 180. Thus:
We know that the measure of A is twice the measure of B. Thus:
And the measure of C is 80 more than the measure of B. So:
Let's substitute A and C into the original equation:
Now, let's solve for the second angle (B). Combine like terms:
Subtract 80 from both sides:
Divide both sides by 4:
So, the second angle is 25 degrees.
This means that the first angle is 2(25) or 50 degrees.
And the third angle is 80+25 or 105 degrees.
And we're done!
The angles are 25, 50, and 105.
